2. Consider a DC series motor, operated at 200V. Eo = ẞI w, with ẞ = 0.125 Vs/A. ме Li R a) The motor is to provide a total useful torque of 0.5 N-m, while operating at 3820 rpm. Find the mechanical power provided by the rotor and the needed resistance, R. b) Increasing the voltage of 300 V, the mechanical power increases to 360W when the resistance is 40 Ohm. Find the corresponding torque in N-m and speed in rad/s.
